Solar panel cleaning that leaves the glass intact
Dust, pollen, soot and bird droppings sit on panel glass and block light. Rain rinses some of it off, but dry seasons, nearby roads, farms and trees leave a film that rain alone does not shift. A proper clean restores the output the dirt was taking.
Worth a call if
- Output has dropped and the weather has not
- You live near dust, farms or the sea
- Birds roost on or near the roof
How we clean
We use soft-bristle brushes on water-fed poles and purified water that dries without spotting. No pressure washers, no household detergents and no walking on panels. We clean early in the morning or late in the afternoon, because cold water on hot glass can stress it.
How often
It depends on where you are. Homes near gravel roads, farmland, building sites or the coast need cleaning more often than a house in a leafy suburb. Two to four cleans a year suits most sites; we suggest a schedule after the first visit, based on how dirty the panels were.
A check while we are up there
Every clean includes a visual check of the array: cracked glass, loose clamps, damaged cables, bird nests under the panels and signs of hot spots. We photograph anything that needs attention and send it to you.

Questions people ask us
Can I clean the panels myself?
If you can reach them safely from the ground with a soft brush and clean water, yes. Do not climb on a wet roof, do not use detergents or pressure washers, and never walk on panels.
Do you clean systems Groenevolt did not install?
Yes. We clean and check any system, whoever installed it.
